摘要
较强鲁棒性的压缩技术成为主流,压缩系统的容错性能变得越来越重要。本文分析了图像压缩中的几种常见容错技术,针对星载遥感图像的特点结合JPEG2000的相关容错技术,提出了适合硬件实现的容错方案。该方案采用Verilog语言设计并在FPGA上经过验证,最后应用在某型压缩平台上,效果良好。
The compression technology with strong robust being mainstream, the error tolerance of the compression system becomes ever importance. This paper analyzes some kinds of usual error tolerance technologies in image compression, especially JPEG2000 tolerance technology, a scheme.which is carried out easily with hardware is presented, and it focuses on Remote Sensing image satellite . The scheme designed with VerilogHDL has been applied to some compression platform at the same time test at FPGA, the effect is good.
